4 Claims.

This invention relates to improvements in securing means and is directedmore particularly to devices for releasably securing objects together.

The principal objects of the invention are directed to the provision ofa device for securement to an object that is adapted for releasablyengaging another object and arranged to hold the objects in releasableassociation.

The device of the invention is adapted for broad application and whileit may be used for securing various objects together it will for purposeof disclosure be described in connection with securing the shield ofradio appaatus to the chassis thereof.

It is customary in radio apparatus to provide a chassis formed frommetal and to secure thereto shields or closures which enclose variouscomponents of the apparatus. Various means have been employed for thispurpose but are diflicult to manipulate and expensive to produce.

According to this invention securing means is provided which is simplein form and is so constructed and arranged as to be automatic inoperation. That is, the device of the invention may be secured to onepart such as a shield and the shield may be'brought into associationwith the chassis or other part in such a way that the parts arerelatively locked in the desired relation.

It will be understood that while the invention will be described inconnection with a shield and chassis of radio apparatus that theinvention is not to be so limited.

With the foregoing and various other novel features and advantages andother objects of my invention as will become more apparent as thedescription proceeds, the invention consists in certain novel featuresof construction and in the combination and arrangement of parts as willbe hereinafter more particularly pointed out in the claims hereuntoannexed and more fully described and referred to in connection with theaccompanying drawings wherein:

Fig. 1 is a front elevational view of the securing device of theinvention shown attached to an object such as a shield;

Fig. 2 is a sectional elevational view on the line 2-2 of Fig. 1;

Fig. 3 is a view similar to Fig. 1 to explain the operation of thedevice; and

Figs. 4 and 5 are side elevational views of another form of deviceembodying the features of the invention.

Referring to the drawings more in detail, the invention will be fullydescribed.

2 represents a shield such as employed in connection with radioapparatus. This is usually in the form of a receptacle which is to beslipped over to enclose a coil, tube or the other component of theapparatus. 4 represents a portion of a chassis or plate with which theshield is to be associated. In radio apparatus it is desired andnecessary that the shield 2 make a good contact with the plate 4.

The device of the invention may take the form of a clip 6 which has aneye 8 that is secured as by a rivet or the like I0 to a wall of theshield. A body portion I 2 of the clip extends from the eye 8 and has anofiset portion [4 which will be disposed in a slot l6 provided in theshield. The offset portion H in the slot l6 prevents turning of the clion the shield. A cam portion N3 of the clip extends angularly from themain body portion l2 and from its upper end there extends in angularlydisposed relationship an end portion 20 which underlies the main bodyportion l2 and has its extremity 22 bent upwardly, as shown. Theportions I2 and I8 are in diverging relation.

The clip will preferably be made from springlike material or materialthat is yieldable or resilient, so that the portions l8, l2 and 20 arerelatively yieldable.

The late 4 to which the shield 2 is to be secured is provided with aclip receiving hole 30. In securing the shield and plate together theyare moved towards one another so that the outer end of the body portion[2 and portion l8 of the clip are inserted in the hole 30. By applyingthe necessary amount of pressure to the parts the part l8 of the clip isacted upon by the edge of the hole 30 so that it is swung inwardlytowards the part [2 whereby the jointure 32 of the parts l8 and 20 orthe wider part of the clip passes through the hole 30. That is, part I8is cammed inwardly or parts l8 and i2 are brought towards one another byopposite edges of the hole so that the wider part of the clip may passthrough the hole. In other words, as the clip is inserted into the hole30 it is contracted and when the jointure 32 has passed through the holethe part l8 swings counterclockwise away from part l2. Then the part 20yieldingly engages the lower edge of the hole 3|] as shown in Fig. 3.

The clip is so constructed and arranged that the part 20 thereof pressesupwardly against the lower edge of the hole 30 with a yielding pressurethereby to hold the shield and plate 4 in the desired assembledcontacting relation.

When it is desired to separate the shield andplate the parts l2 and i8may be squeezed towards one another thereby to reduce the overall widthof the clip so it may be withdrawn through the hole. Or in another way,the part 20 or the part 22 of the clip may be pushed on so as to bringabout the desired reduction of the overall width of the clip.

In the form of the invention shown in Figs. 4 and 5 the end portion 22is bent upwardly and extends across the main body portion as at 23 withits extremity 25 bent outwardly.

The part 22"in all forms of the clip acts as a stop to limit spreadingof the parts l8 and [2. The part 25 abuts the side of the body [2 tolimit relative movement thereof when the parts l2 and I8 are squeezedtogether.

The invention may be embodiedin other spe-,

cific forms without departing from the-essential characteristicsthereof. Hence, the present embodiments are therefore to be consideredin all respects merely as being illustrative and not as beingrestrictive, the scope of the invention being indicated by the appendedclaims rather than by the foregoing description, and all modificationsand variations as fall within the meaning and purview and rangeofequivalency of the appended claims are therefore intended to be embracedtherein.

What it is desired to claim and secure by Letters Patent of the UnitedStates is: r

1. A device of the'class described for securing objects togethercomprising, a clip formed from a'single'length of yieldable wire tohave, a portion at its upper'end for securing to an object, a bodyportion extending therefrom, a cam portion extending upwardly in adiverging relation from the lower-end of said body portion at one sidethereof, an end-portion extendin in a diverging relation from the upperend of said cam portion having an endmostportion disposed rearwardlyofsaidbody portion and provided with an extremity extending outwardly atan opposite side of the body portion, and across said body portion andthen inwardly, said outwardly and inwardly extending portions adapted toengage said body portions to limit movements of the cam and end portionsrelative'to the body.

2. A device of the class described for securing objects togethercomprising a member made from a. length of yieldable wire having anupper part for securing to an object and a body portion extendingdownwardly therefrom, a cam portion diverging upwardly from the lowerend ofsaid body portion, an end portion diverging from the upper end ofsaid cam portion and extending adjacent said body portion, and anextremity of said end portion bent upwardly at a side of said bodyportion to limit the divergence of said body and cam portions.

3. A device of the class described for securing objects togethercomprising a clipformed from a single length of yieldable wire havingaportion at its upper end for securing to an object, a body portionextending downwardly therefrom, a cam portion diverging upwardly fromthe lower end of said body portion at one side thereof, an end portiondiverging from the upper end of said cam portion and extending beneathsaid body portion, and the extremity of said end portion extendingupwardly at an opposite side of said body portion to limit thedivergence of said body and cam portions.

4. The combination of an object and a device for securing said object toa second object in which said securing device comprises a clip formedfrom a single length of yieldable wire having an upper part forarticulately securing said device to said object, a body portionextending downwardly therefrom, a cam portion diverging upwardly fromthe lower end of said body portion, an end portion diverging from theupperend of said 'cam portion and extending adjacent said body portion,an extremity of said end ;-portion bent upwardly at a side of the bodyportion to limit the divergence of said body and cam portions, said bodyportion being provided with an oifset portion disposed between its upperand lower ends, and said object havin an aperture so as to receiveanother offset portion, whereby said body portion is maintained in fixedrelationship to said object.
